Elastomeric compression preloaded support insulators

Abstract

Elastomeric compression preloaded support insulators for automotive drive shafts.

What is claimed is: 
     
       1. An elastomeric compression preloaded support insulator for automotive drive shafts, said insulator comprising a unitary structure comprised of concentric circular portions including:
 (a) an outer rim having an outside surface, having outside edges that project perpendicular to the outside surface; 
 (b) a center portion essentially centered in an inside surface of the outer rim, said center portion having a lower front edge; 
 (c) a hub, said hub projecting laterally from the lower front edge of the center portion, there being a centered opening in the insulator, there being a series of openings through the outer rim. 
 
     
     
       2. The insulator as claimed in  claim 1  further comprising a series of openings through the outer rim. 
     
     
       3. The insulator as claimed in  claim 1  wherein the insulator has a snap closure and it is glued during installation. 
     
     
       4. The insulator as claimed in  claim 1  wherein the insulator is split and is glued during installation. 
     
     
       5. The insulator as claimed in  claim 1  wherein the insulator is split and is pinned together during installation. 
     
     
       6. The insulator as claimed in  claim 1  wherein, in addition, there are ties located in the openings.
